Benefits of technology

In accordance with the invention, the foregoing advantages have been achieved through the present air filter system for use in a refrigerator having a fresh food compartment, having a plurality of planar wall surfaces, and a freezer compartment with an air return passageway disposed in fluid communication between the fresh food compartment and the freezer compartment. The air filter system for filtering at least some of the air flowing from the fresh food compartment through the air return passageway into the freezer compartment, of the present invention, may include: a housing having an interior defined by a plurality of wall members formed integral with each other, each wall member having an inner surface and an outer surface; at least two of the wall members having integrally formed on each of their

Problems solved by technology

Additionally, some refrigerators manufactured in Japan utilize a ceramic filter built into the refrigerator; however, the filter is not changeable, and only lasts approximately seven years.
The present devices of the types previously described have m

Example

In FIG. 1, a refrigerator 60 of the present invention, is shown to generally include a refrigerated, fresh food compartment 70, having a plurality of planar wall surfaces 71, 72, 73, 74, and 75, the door of refrigerator 60 not being shown for drawing clarity purposes. Refrigerator 60 further includes a freezer compartment 80, and an air return passageway 81 is disposed in the lower, or bottom, wall surface 73 of fresh food compartment 70, and air return passageway 81 is in turn disposed in fluid communication between fresh food compartment 70 and freezer compartment 80, as is known in the art. At least one air filter system 90, and in the case of refrigerator 60, two air filter systems 90 are illustrated (in an exploded fashion in FIG. 1) for filtering at least some of the air flowing from the fresh food compartment 70 through the air return passageways 81, into the freezer compartment 80. The return air passageway 81 preferably includes a plurality of openings 82, which openings ar...

Abstract

An air filter system for refrigerators includes an economically and easily manufactured housing having a replaceable air filter supported within the housing, and a releasable connector associated with the housing permits the housing of the air filter system to be readily and easily removed from the refrigerator, to permit the easy replacement of the air filter.

Description

1. Field of the InventionThe invention relates to an air filter system for use in a refrigerator, and a refrigerator having an air filter system which filters air flowing between the fresh food compartment of the refrigerator into the freezer compartment of the refrigerator.2. Description of Related ArtVarious devices have been proposed over the years to filter air from the refrigerated, fresh food compartment of a refrigerator, to reduce food odors in the compartments of the refrigerator, as well as reduce odors in the air flowing back into the freezer compartment. By reducing food odors in the refrigerated, fresh food compartment of a refrigerator, odors in ice made in the freezer compartment, as well as the taste of such ice is improved.Such devices have included fans, glow discharge lamps, ozone decomposing catalysts, deodorant blocks, particles of activated carbon, and ultraviolet lamps operative to radiate an ultraviolet ray to a photocatalyst layer, among others. Additionally...
